These devices, as well as the discharge Carrier also provides additional guidelines for the safe use piping, must not impair operation or lead to a pressure drop that of R1234ze(E) refrigerant that should be added to the is higher than 10% of the set pressure. - Page 6 Under certain conditions they permit connection of several valves to the same discharge pipe. Carrier recommends using flexible hose to connect the relief valves to discharge pipe. Special care shall be taken so that coupling to discharge pipe is not creating mechanical stress on relief valve connection.
